The JL Overland Boost kits are specifically designed to lift your JL and maintain factory spring rate, compliance and ride quality while having the option of retaining factory shocks, maintaining full wheel travel with use of shock extensions (part number EXT kits) or without shock extensions to allow for use of your choice of aftermarket 2/2.5” lift shocks. In using rigid steel coil spacers we maintain the factory ride quality without effecting or lowering spring rate like the alternative compressible plastic or poly urethane spacers.

The difference with EVO MFG Overland Boost systems vs EVO MFG Boost systems is the use of front control arm drop brackets. When lifting you vehicle your control arms at ride height have a steeper angle towards the floor which can have some negative effect/chop in ride quality. With the use of the included Overland Control Arm drop brackets while lifted we maintain factory flat control arm angle alleviating much of the chop associated with lifting a Jeep giving even better and more improved ride quality. Also in the use of Overland Drop Brackets we are able to engineer more performance into the front suspension to improve braking and driveline angles through suspension cycle. EVO MFG JL Overland Boost kits are available in multiple configurations. These Overland Boost kits will fit up to a 37” tires on Rubicon Model JLs or 35” tires on Sahara and Sport/S

The EVO MFG 2.5" JL Boost and Overland Boost are very easy to install
using normal tools. No drilling or cutting (optional rear shock
extensions require one minor drill). They require no driveshaft or
exhaust modifications. Simple Bolt on installation.
